IMPROVEMENT m WATER-METERS.

The Schedule referred to in these Letters Patent and making part of the sama.

To all whoml it may concern Be it known that we, OLIVER B. GRIGGS, of Manseld, and EDWIN A. BARRoWs, of Windham, both in the State of Connecticut, have invented a new and improved Liquid-Meter and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, in Which- Figure 1 is a front elevation.

Figure 2, a vertical section of the case, the front plate, with the working-parts, being shown removed. This section is on the plane :z: x, iig. 3.

Figure 3 is a transverse IVertical section.

Figure 4, a side elevation.

Like letters indicate corresponding parts in all of the views.

Our invention consists of a cylindrical case, having 'a radial piston alhxed to a central hub or axis, and a fixed partition or butrnent extending from said hub to the periphery, said piston being alternately moved in opposite directions around `the circle of the Cylinder, from one side of the butment to the other, by the successive iilling of the chamber with liquid from the induction-pipe, and actuating a lever and weight outside ofthe ease, which, by falling, shift the induction-valve, and also actuatethe registering-wheels by means of a lever and pawl.

As represented in the drawing, A A is the external case, and a, the piston which moves in the chamber b b, in alternately opposite revolutions, and is stopped before reaching the butment, or permanent division, by the) shifting of the induction-valve, as hereafter described.

'lhc induction-pipe g and eduction h are connected with the case, at or near the junction of the butment therewith.

The same Valve, j, serves both, having waysfor the induction and eduction, and is changed, to eifect the filling of the chamber, through inductions i i, on each side of the hntment, as hereinafter explained.

lhc water, or other liquid, entering through the pipe g, in the direction of the arrows, moves the pistou around to the opposite side of the butmcnt c, when the chamber having become iilled, and the induction being instantly changed to fi, the piston is actuated iu the reverse direction, the water, at the same time, escapin g through the eduction-way h, while the chamber is being again iilled. 1

-An arm, (I, of the hub of the piston extends through the front side of the case, and has attached to its end the rigid' pin c.

Pivotcd loosely on this is the lever 1:, having two equal arms, and the ball or weight P.

A rod, j, connects one end of the level' L' with a disk or arm, o, attached to thc valve-stein j, so that the motion imparted to thc-lever issimultaneously transmitted to the valve.

llhis connection may be made by segmental gears on the parts k and o.

The pistou-arm d turns freely iu the level', but aS the piston is traversing around, the pin c is engaged with ore of two fixed pins m m, on the arm of the ball P, and carries the latter past the centre of gravity,

when it suddenly falls on the lever k, and, by its weight, moves it far enough toshift the position of the valve f, so that the water is cut olf from the .chamber on the side of the butinent from which it has been lfilled, and made to e'nter on the opposite side of the piston as the water admitted by the last stroke is escaping from the cylinder.

While water is being steadily drawn, this action is continuous, thepiston moving alternately in opposite directions, and the weight changing the position o f the valve, by falling first on one arm of the lever la and then on the other. l

As the motion of the valve f ,is instantaneous, and is not directly communicated by the piston a, there is no liability to stoppage of the meter, when the valve is in its middle position, as is the ease in many meters.

A modification of this valve will admit of its occupying the chamber b b. This consists in placing the induction and eduction=pipes both upon the back of i lthe case, having each extended through the case by chambers elongated horizontally and bisected bythe butment c. These chambers are covered with a disk, having two openings corresponding in position with the chambers, but smaller, so that the oscillation of the disk places the opening alternately in connection with the induction and ednction, on opposite sides of c. The movement of the valve is effected in the same manner as the other.l

A pin, n, attached to the -lever la, operates a lever, which works a pawl engaging with a toothed wheel in the register, gearing, and thereby putting in motion, a seriesof indexes, for recording the amount of liquid which passes through the cylinder, the contents of which are made to equal some definite measure; and, as this quantity must be equal in each, oscillation of '-the piston, the water measured will be correctly indicated on the register.

The front side of the cylinder is made movable, and l is secured to the back by bolts passing through the two sides. A spring may be applied to operate the valves, instead of the weight-With equivalent effect.

The apparatus :is simple, cheaply constructed, dura ble, and invariably reliable in its operation.

What we claim as our invention, and desire to seeure by Letters Patent, is

1. The weight P and lever k, mounted on the same arm with the rotary piston a, in combination with said piston, the pins e m m, and rotary valve f, and operating substantially as and for the purpose described. 2. In combination therewith, the lever l and registcring-zuiparatus R, substantially as and for the purpose described.

In witness whereof, we have hereunto signed our names, in the presence of two subscribing witnesses.
